Introduction
A subcontractor invoices £50,000 of labour in a month and plans wages and suppliers around being paid in full. Then an HMRC letter arrives questioning its gross payment status. If that status is withdrawn and its contractors start deducting 20%, the next month’s cash receipts could be £10,000 lower. The tax has not increased by £10,000. The timing of the cash has changed – and that may be enough to disrupt the business.
That is why gross payment status is not a one-off registration exercise. A qualifying construction subcontractor has to keep its business records, relevant tax returns and payments in order long after HMRC approves the application. Accountants need to understand the three entry tests, the review process and the difference between an initial warning and a cancellation notice.
This guide covers what gross status is worth, the business and turnover tests, the compliance test in operational terms, the annual review cycle, appeals, and the controls a UK accountancy practice can put in place before a problem reaches the client.
Gross payment status changes when a construction subcontractor receives its money, not whether it ultimately owes tax. Contractors normally deduct CIS tax at 20% for registered subcontractors without gross status or 30% at the higher rate; approved gross-status businesses are paid without CIS deductions. That distinction can be critical where a business must cover weekly payroll, hire charges and materials before its customers settle.
What gross payment status is worth in cash terms
| Monthly CIS payment | Under 20% deduction | With gross status |
| £50,000 labour payment | £40,000 received | £50,000 received |
| Amount withheld at source | £10,000 | £0 |
Gross payment status protects working capital by allowing qualifying subcontractors to receive payments without deductions at source.
For firms advising subcontractors, a monthly receipt forecast should sit alongside accurate CIS return records so changes in deductions can be identified before payroll and suppliers fall due.
Imagine £50,000 per month of labour payments that would otherwise be subject to a 20% CIS deduction. The customer would usually retain £10,000 each month under deduction, while a gross-paid business receives the entire £50,000. Over a year, the timing difference could be £120,000. This is not a permanent tax saving: final liabilities still arise through the relevant income tax or Corporation Tax processes.
In a cash forecast, compare anticipated receipts by contractor, payroll weeks, major material purchases and expected tax settlements. Gross status should not be used as a substitute for ring-fencing money to meet future liabilities. A business relying entirely on undeducted receipts without providing for tax can simply move its cash-flow problem to the year end.
For a simple numerical comparison, Monthly labour paid £50,000; CIS deduction at 20% £10,000; cash under deduction £40,000; gross receipt £50,000.
The business test: construction activity and a bank account
An applicant must operate a qualifying UK construction business and meet the business-test requirements, including using a bank account.
The application should reflect genuine business activity: contracts, payment records and an account through which business transactions can be evidenced. Accountants should reconcile the declared trading model to subcontractor invoices, contracts and accounting records. An application built on a generic trade description is more likely to generate follow-up questions when the underlying evidence suggests a different arrangement.
A company can act both as a contractor making payments under CIS and as a subcontractor receiving payments. Those are separate obligations. Having gross payment status as a subcontractor does not cancel the need to verify and deduct from subcontractors it pays. This distinction is especially relevant for labour-only firms that increasingly subcontract work.
The turnover test: calculate qualifying net construction turnover
The ordinary turnover requirement is £30,000 for a sole trader, with specific alternatives for partnerships and companies.
A sole trader generally needs net construction turnover of at least £30,000 in the relevant 12 months. For a partnership, the ordinary test is £30,000 per partner or £100,000 overall; comparable rules apply to companies by reference to directors and an alternative £100,000 threshold. Detailed provisions apply to certain close companies and exceptional applications. A reviewer should check HMRC’s prevailing rules for the specific legal structure.
Do not use total invoice value as the turnover test. VAT and materials are excluded when determining net construction turnover. For a firm billing £210,000, of which £42,000 relates to qualifying materials and VAT is separately charged, the relevant construction turnover may be materially below the headline sales figure. Build a traceable schedule that links invoices, the labour component and the calculation supplied to HMRC.
The compliance test, including VAT compliance since April 2024
HMRC tests a business’s wider tax compliance, not just whether its CIS returns were submitted.
The relevant qualifying conditions are explained in HMRC’s CIS 340 guidance; record tax filings and payment evidence in a single compliance file instead of relying on a year-end checklist.
HMRC can consider tax return filing, relevant payments and associated statutory obligations. Since 6 April 2024, VAT compliance is also part of the gross payment status compliance test. Late VAT filings therefore create a risk even where labour contracts are profitable and annual construction turnover comfortably exceeds the minimum.
Statutory tolerances can protect a business from losing status for certain minor failings. Those tolerances have conditions and should never be treated as permission for repeated late filing or payment. A practice should monitor PAYE, CIS, VAT, Self Assessment or Corporation Tax as relevant, with documented owners and a monthly review of submissions and HMRC balances.
An effective exception register names each outstanding return, deadline, date submitted, sum due, payment reference, person responsible and evidence of resolution. It is more useful than an annual declaration saying that the client believes its taxes are up to date.
HMRC annual reviews and the sequence of letters
HMRC reviews existing gross payment status annually and may seek explanations before ordinary withdrawal.
A notice should be checked against actual returns and payment histories, not accepted uncritically. Sometimes the issue is a misallocated payment, mistaken tax period or a return shown as missing despite an acknowledgement. A concise reconciliation and documentary evidence can be more persuasive than a long general explanation.
A warning is not identical to a final cancellation. HMRC’s ordinary annual-review process provides an opportunity to explain failures; a later withdrawal notice specifies the decision and appeal rights. Serious non-compliance can involve different, faster action, so advisers should read the particular notice and not rely on a generic timeline.
What triggers cancellation and how to respond
Repeated or material failures can trigger withdrawal; serious non-compliance can lead to faster cancellation under the current rules.
Possible triggers include failures to submit returns, unpaid amounts and inaccurate information relevant to eligibility. From April 2024 HMRC has stronger powers in qualifying serious non-compliance cases. An immediate response should quantify the client’s monthly gross receipts, identify contractors who may change deduction rates and update a 13-week cash forecast.
Prepare an HMRC issue schedule with five columns: allegation, relevant period, evidence available, correction or explanation, and next deadline. Where the assessment is justified, rectify the underlying filing or payment problem promptly and do not invent explanations. A transparent account of the steps taken is preferable to a defensive narrative unsupported by documents.
Appeals and what happens after losing status
An ordinary withdrawal notice normally allows 30 days to appeal; follow the specific notice and HMRC procedure.
HMRC describes ordinary withdrawal as taking effect after a notice period, generally 90 days, subject to the applicable process. An appeal should identify the decision, explain the alleged error, show the relevant dates and attach submission receipts or bank evidence. Keep a record of correspondence and escalate promptly if the client has received a different type of cancellation notice.
If status is ultimately cancelled, HMRC’s ordinary guidance indicates that reapplication is generally not available for one year. During the period under deduction, reconcile CIS tax suffered carefully so the client can claim credit under the correct mechanism: Self Assessment for individuals and partnerships, and the applicable PAYE offset process for limited companies.
A year-round CIS compliance control checklist
Treat gross status as a recurring compliance obligation with clear monthly, quarterly and annual controls.
Construction clients often need linked construction accounting support and bookkeeping reconciliations to explain differences between HMRC accounts, source records and contractor payments.
Each month, reconcile the bank, sales ledger and CIS deduction statements received; confirm VAT and PAYE returns, check HMRC payment allocations and archive submission confirmations. Each quarter, monitor net construction turnover, cash provision for taxes and any subcontractor onboarding changes. Before the expected annual review, investigate all unresolved returns or liabilities.
For a UK practice serving dozens of subcontractors, consistency matters more than an elaborate spreadsheet. Use the same evidence standard for every client and a clear escalation trigger for the partner or manager when a filing is missed or an HMRC notice arrives. Probal Global can help prepare reconciliations and reviewer-ready working papers through its CIS support service.
Decision tree: what to do after an HMRC letter
First identify whether the letter is an information request, proposed failure, withdrawal decision or serious non-compliance cancellation. Second, calendar the specific response or appeal deadline. Third, reconstruct the reported failure from HMRC online records and bank receipts. Fourth, prepare a cash-flow sensitivity comparing 0% and 20% deductions. Finally, send a documented response approved by the client’s adviser.
Data to give a reviewer before sign-off
A high-quality review pack includes current trading details, the net construction turnover schedule, tax-return acknowledgements, payments against HMRC liabilities, all unresolved correspondence and a short explanation of any tolerances relied on. These records make the final decision traceable and help the practice respond to queries quickly.
Why this matters to UK accountancy practices
The benefit is not another list of rules. It is a consistent process that links source documents to reporting, exposes exceptions before deadlines and produces a concise working paper for the senior reviewer. The practice retains responsibility for technical judgement, client advice and final approval. The bookkeeping or preparation team should never guess at a legal classification simply to complete the monthly file.
Probal Global positions its services as an extended back-office team for UK firms. The practical outsourcing boundary is clear: transaction processing, schedules, reconciliations, return preparation and exception tracking can be delegated; fact-sensitive tax decisions, client instructions and final sign-off remain with the appointed adviser.
A worked compliance review: what the accountant should send HMRC
Suppose HMRC reports a late VAT submission during an annual review. Start with the precise tax period, not a broad statement that the client always files on time. Obtain the submission receipt, the account history, the VAT return reference and any correspondence about an HMRC service problem. Compare the statutory due date with the recorded submission date and identify whether the failure falls within a permitted tolerance or requires an explanation.
The client file should contain a dated issues schedule and copies of the evidence actually supplied. Where the failure is genuine, explain what happened, any applicable reasonable-excuse position and what permanent control has been introduced. An appeal is stronger when it deals with each alleged failure on its facts, rather than relying on the business’s general commercial importance.
Frequently asked questions
Does gross payment status mean I pay no tax?
No. It changes collection at source; taxable profits and other liabilities remain assessable under the normal rules.
Can a new subcontractor qualify?
Potentially, provided it satisfies the applicable tests or a statutory exception. Check the exact eligibility requirements for its structure.
Can a late VAT return affect gross status?
Yes. VAT compliance has been considered in the test since 6 April 2024, subject to the statutory framework and tolerances.
Does HMRC review gross status annually?
Yes. HMRC carries out annual compliance reviews of businesses retaining gross payment status.
How long is the normal appeal period?
Ordinarily 30 days from the relevant decision notice; confirm the rights and date on the specific notice.
Can a limited company reclaim CIS deductions suffered?
Yes, through the appropriate company reporting and PAYE offset arrangements rather than claiming them as a sole trader would.
Is turnover measured before or after materials?
Qualifying net construction turnover excludes VAT and the cost of materials for this test.
What should an accountant check before HMRC reviews?
Submission acknowledgements, tax payments, reconciliations, outstanding notices and business eligibility evidence.
What should I do when a contractor suddenly starts deducting CIS?
Ask the contractor to verify the subcontractor’s current CIS payment status and obtain the relevant HMRC notice. Do not assume that the contractor has made a mistake: its deduction obligation follows the status confirmed to it. Reforecast cash receipts, reconcile deductions suffered and investigate whether a status review or cancellation decision requires a response.
Does paying a disputed tax bill preserve gross status?
There is no universal answer. The impact depends on the type of liability, payment obligations, the compliance-test rules and the facts of the dispute. Record the dispute, preserve correspondence and determine whether the relevant payment or filing failure is a qualifying failure. A formal payment arrangement should also be documented rather than inferred from informal discussions.
How Probal Global supports UK accounting practices
The worst moment to discover a missing VAT return is after HMRC has questioned gross payment status. The best safeguard is ordinary, documented compliance carried out every month. For a UK firm managing several subcontractors, that means reconciled source records, dated filing evidence and early escalation of exceptions — not a rushed exercise when a notice arrives.
For firms carrying this work across multiple clients, the preparation challenge is maintaining clean source data, reconciled balances and an audit trail that the UK reviewer can follow. Probal Global supports UK accountancy practices as a back-office preparation team. The firm retains the client relationship, professional judgements and final sign-off; the outsourced work is built around its existing process and software.
